Sigmoidscopy is thought to be one of the basest and most essential tools for evaluation of colorectal patient because it could be performed in an out patient clinic with only minimal bowel preparation. AIM: The aim of this study was to assess the patient's best position for sigmoidoscopy. MATERIALS AND METHODS: Between March 4, 1997 and April 18, 1997, all patients who visited the colorectal clinic at the Dept. of Surgery, Korea Veterans Hospital were alternately underwent sigmoidoscopy in these four different positions: supine(S), left lateral(L), right lateral(R), and jack-knife(J). Sigmoidocopy was routinely performed for all patients who had lower gastrointestinal problems and was done by two well traind surgeons who had performed more than 100 sigmoidoscopies previously to this study, The patients who could not be tolerate insertion of the total length (60 cm) of the sigmoidoscope due to poor bowel preparation and/or complete obstruction by a mass were excluded. We evaluated the patient's complaints according to minimal, moderate, and severe discomfort and time between start and complete insertion of the 60 cm length of the sigmoidoscope. Statistical analysis was performed by an appropriate Anova test and Fisher's exact test. RESULTS: There were no differences among these four groups relative to age(5; 58.0+/-12.7, L; 64.3+/-10.0, R; 62.0+/-10.1, J; 56.0+/-12.9), gender(5; 76%, L; 70%, R; 72%, J, 83%,male ratio), degree of discomfort (mild: 42.9% (5), 50% (L), 33.3%(R), 66.7%(J), moderate: 42.9%(5), 34.6%(L),25%(R), 13.3%(J), severe: 14.3%(5), 15.4%(L), 41.7%(R), 20%(J)) and duration of insertion of the sigmoidoscope(5; 264.4 +/-192.9, L; 226.5 +/-267, R; 301.6+/-361.3, J; 202.5 +/-117.8 seconds). Also, there were no statistical significances between the two groups according to the surgeon who performed the procedure. CONCLUSION: The best position for sigmoidoscopy does not depend on the patient's position. Therefore, allowing the patient to change his position during the procedure would be the best way for an easy and comfortable sigmoidscopy.

Although malignant melanoma usually occurs after the diagnosis of vitiligo-like depigmentation, the latter is rarely followed by the former. We herein report on such a case in which recognition of the vitiligo-like depigmentation preceded diagnosing the metastatic melanoma by several months. A 56-year-old woman had first developed vitiligo-like depigmentation on the forehead, eyelids, neck and back 18 months previously and thereafter she detected a hard mass in the left axilla 2 months previously. Based on the histologic findings, the axillary mass was diagnosed as metastatic melanoma. To evaluate the primary tumor focus, thorough examinations that included PET-CT, bone scan and sigmoidoscopy were performed, but we couldn`t find any the original primary tumor. Our case suggests that the vitiligo-like depigmentation could be a sign that heralds metastatic melanoma.

BACKGROUND: It is generally accepted that most colorectal cancers develop from adenomas, so the detection and removal of them can reduce the incidence of colorectal cancers. Sigmoidoscopy is the effective tool for detecting and removing adenomatous polyps in the rectosigmoid region, but its major limitation is that sigmoidoscopy alone can not detect considerable portion of colorectal adenomas. METHODS: From October, 1996 to August, 1997, we performed 2017 sigmoidoscopies and 1683 colonoscopies. We analysed the anatomical distribution of adenomas and compared the detection rate of adenomas between two groups. In 32 cases, adenomas detected by sigmoidoscopy were followed by colonoscopy in less than 2 months. RESULTS: We found 125 cases of adenomas in 2017 sigmoidoscopies and 281 cases of adenomas in 1683 colonoscopies. In 281 cases of adenomas found by colonoscopy, 151 cases had rectosigmoid adenomas only and 25 cases had rectosigmoid and proximal adenomas, 105 cases had proximal adenomas only. The detection rate of adenomas by sigmoidoscopy was significantly lower than that by colonoscopy in the rectosigmoid region(6.1% vs. 10.5%, p=0.002). In 32 cases of adenomas found by sigmoidoscopy that were followed by colonoscopy, 7 cases of proximal adenomas and 6 cases of additional rectosigmoid adenomas were detected. CONCLUSION: Sigmoidoscopy cannot detect adenomas in the proximal colon beyond the sigmoid, it also can miss a significant portion of adenomas in the rectosigmoid.

OBJECTIVE: To evaluate the efficacy of MRI in bladder or rectal invasion of cervical cancer. METHODS: Between January 2000 and December 2005, 106 cervical cancer patients who underwent cystoscopy or sigmoidoscopy examination retrospectively compared with results of the MRI finding. A 5-point invasion score was used to determine bladder or rectal invasion in MRI (1 = no invasion, 3 = serosal invasion, 5 = definite mucosal invasion). Score of 3 or above was suspicious for both rectal and bladder invasion. RESULTS: Eighty one patients with negative for both rectal and bladder invasion in MRI were normal in cystoscopy and sigmoidoscopy. MRI identified 17 patients with suspected bladder invasion, 7 patients had confirmed bladder invasion in cystoscopy. MRI identified 11 patients with suspected rectal invasion, 1 patients had confirmed rectal invasion in sigmoidoscopy. The detection of rectal and bladder invasion by MRI had a negative predictive value of 100%. CONCLUSION: The use of a 5-point scoring system for predicting rectal or bladder invasion in MRI is accurate in detecting cervical cancer patients with no evidence of rectal or bladder invasion. The cervical cancer patients with no evidence of rectal or bladder invasion in MRI can obviate invasive cystoscopy and sigmoidoscopy.

BACKGROUND/AIMS: Acute lower gastrointestinal bleeding (LGIB) is a common disorder that requires hospitalization. Colonoscopy is considered as the procedure of choice for diagnosing acute LGIB. The aim of this study was to analyze the clinical characteristics, endoscopic diagnosis and clinical course of acute LGIB. METHODS: From January 2000 to August 2007, 117 patients with hematochezia, who visited Yeungnam University hospital emergency center and underwent colonoscopy or sigmoidoscopy, were reviewed retrospectively. The male to female ratio was 2.25 (81:36). The mean age was 59.1+/-16.9 years. RESULTS: The mean time from presentation to endoscopy was 12.6 hours. The cause of bleeding was identified in 88.9% of the cases after endoscopy. The causes of the acute LGIB were colitis: 26 cases, post polypectomy bleeding: 17 cases, colon ulcer: 16 cases, diverticular bleeding: 13 cases, colon cancer: 9 cases, angiodysplasia: 7 cases and hemorrhoid: 6 cases. Thirty six patients were treated by the endoscopic method; the mean duration of admission was 10.6+/-10.0 days and the mean amount of transfusion was 3.0+/-1.9 U. Those numbers showed statistically significant differences according to the diagnosis. CONCLUSIONS: The most common cause of acute LGIB was colitis and the causes of bleeding were a significant factor that affects the severity of bleeding and the duration of admission.

Leiomyoma of the rectum is a rare tumor and it usually present in 40 to 60 year-old individuals, and it is more frequent in men. It originates from either the muscularis mucosa or muscularis externa and those arising from the muscularis mucosa are typically small and they are identified incidentally in patients who are undergoing sigmoidoscopy. In contrast, the larger leiomyomas arising from the muscularis externa generally present symptoms that are consistent with rectal stenosis or a rectal mass. Endoscopic ultrasonography can help to define the tumor location, extension and size. Surgical resection is the treatment for most leiomyomas of the rectum, but endoscopic electroexcision is a safe and appropriate treatment for small polypoid rectal leiomyoma. We report here on a case of a semipedunculated rectal leiomyoma in a 59 year-old female patient. It was found incidentally during a colonoscopic examination and it was diagnosed by endoscopic ultrasonography. We performed endoscopic mucosal resection with colonoscopic snare electrocoagulation.

Colorectal injury related to anorectal manometry is very rare and is mostly associated with previous rectal surgery. We experienced two cases of colorectal injury related to anorectal manometry in patients without a history of surgery. The anorectal manometry finding of the first patient suggested rectal hyposensitivity, and the maximum tolerable volume was measured as 350 mL. After anorectal manometry, she complained of hematochezia. Sigmoidoscopy showed a deep 5 cm ulcer with vessel exposure at the rectum. She recovered after conservative treatment. In the second case, rectal bleeding occurred while measuring the maximal tolerable rectal volume. A 2.5 cm mural defect and 4 cm mucosal defect were detected in the rectosigmoid area at sigmoidoscopy. Computed tomography showed intraperitoneal free air around the distal sigmoid colon. She improved after conservative management. We suggest that anorectal manometry be performed with great caution, even in patients without a history of surgery.

Actinomycosis is an indolent, slowly progressive infection caused by actinomyces species that normally colonize the mouth, colon, and vagina, characterized by sulfur granule formation. Actinomycosis can affect multiple organs, with local or systemic manifestations. The abdomen is involved in less than 20% of the cases with the ileocecal area being the site most frequently affected. The anorectal region is less frequently involved. We report a case of anorectal actinomycosis, which was diagnosed by histologic study of sigmoidoscopic biopsy. The patient was a 40-year-old man who took immunosuppressive agents after kidney transplantation. Adequate surgical excision was done, being followed by administration of massive dose of a penicillin.
